The number and type of copper centers, EPR parameters, and the two relevant absorption bands in the visible region for several representative members of the blue oxidases are listed in Table II. All laccases except that of the P. radiata enzyme contain four coppers per molecule with one type-1, one type-2, and one type-3 copper center. The EPR and absorption parameters resemble each other very much. Phlebia radiata laccase is supposed to contain only two coppers with one type 1, one type 2, and one PQQ per mole (70). This is quite unusual and will be discussed critically below, since it is possible that the copper content determined for this enzyme is inaccurate. Ascorbate oxidases have eight coppers per homodimer with two type-1, two type-2, and two type-3 copper centers. Ceruloplasmin typically contains six to seven copper ions per molecule with three type-1, one type-2, and one type-3 copper centers. It has also been proposed that there are only two type-1 copper ions and a new type-4 copper that is presumed to exhibit no EPR signal. In addition there is a variable content of chelatable copper. It is responsible for copper contents exceeding 6 coppers/mol but does not seem to be required for catalysis. It is now generally accepted that ceruloplasmin has three type-1 copper centers and the reason for this will be discussed below.

The ceriporiones are closely related to the antibiotic merulinic acids, e.g. merulinic acid-A (417), which have been isolated from fruit bodies of Merulius tremellosus and Phlebia radiata 275).
